I’m okay stressed out cuz homework haha
We can use substitution or elimination
Let’s use substitution
Make slope intercept equation for the first equation
Y = -x + 5
Now plug in the y value for the second equation
-5x - 4(-x + 5) = -18
-5x + 4x - 20 = -18
-1x = 2, x = -2
There is one solution
All interior angles are equal to 180. Because a right triangle has one 90 degree angle. The sum of the two interior angles is equal to 90. Because both the interior angles are the same, each one measure 45 degrees
Answer:
Step-by-step explanation:
For the given equation :
Making the coefficients of x to L.H.S
Taking 3 as common from the above equation
Splitting the equation to make factors
Taking common from the equation:
Equating 'x' to zero
False -3 and 3 because 3×3=9 the same for -3.
-3×-3=9
